Thats the one. Thats the problem with that button for some strange reason. It is one button in the frame but for some reason it isn't working in nUI but worked when I had a temp mover fix set up for it a whiles back.

Do a search for Ultraxion in the nUI forums and find some posts relating back to before the 5.0.4 patch hit and you should see a mention of the macro for it, just in case I spelt it wrong.

Until I can get in and test it out myself next week I can't do anything unfortunately. Its hard to blind fix a problem if you don't know where the problem is
